The corresponding grip piece ,11 is similar in construction excepting that its hooked extremity is of such a shape as to permit the frameand the rear extremity of the firing pin abuts against the rear wall of the receiverframe or section 1, such impingement causing the firing pin to contact withthe cartridge and eject the same laterallythrough the side opening-13 of the barrel frame section 14. The face of the breech block, furthermore, is suitably grooved as indicated at 15 beneath the grip pieces'lO and 11 so as to guide the cartridge from the magazine to said grip pieces through the instrumentality of the cartridge carrier hereinafter described. The forward portion of the barrel section 14 is provide'd'with a short passage 16 which communicates with the magazine for the rifle of which 17 desig= nates the outer shell and 18 the inner shell, said magazine being provided with the usual follower 19. all ofconventional construction so that no further description is deemed necessary in respect to this feature.

Reverting to the breech block it will be observed that its forward end is provided with spaced legs 20, 21, the latter being longer than the first mentioned leg for reasons which will appear hereinafter. In addition thebreech block at its upper portion is formed with a recoil projection or lug 22 which in closed position of the'breech block is received in the recoil recess 23 formed in the barrel section of the receiver. Both the receiver frame and stock sections are grooved as indicated at 2-1 in Fig. 8 of the drawings to receive the breech block for reciprocation and it will be apparent that this is advantageous in that it prevents the accidental displacement of the breech block when dismantling the rifle for repair or cleaning purposes.

The breech block is adapted to be reciprocated or actuated by means of the actionbar or slide 25 shown most clearly in Figs. 16 and 17, the forward end of'said action bar being connected to the grip piece or forearm 26. The action-bar is longitudinally grooved at its rear portion as indicated at 27 and one of the side members thereof carries the spring'actuated dog 28, the extremity of which projects laterally into the slot 27 The opposite leg of the action-bar has formed in its uppersurface a recess 29 which conforms in shape and configuration to the cam extension 21' of the leg 21 of the breech block. The last-mentioned leg of the action-bar is longer than the one carrying the'dog 28 and thereby provides an extension 25 upon which the cam extension 21' of the breech block normally seats so that when said breech block is in closed position the recoil projection 22 is held in the recess 23. The cam extension 21' and its correspondingrecess 29in the action-bar constitutes the operative connectionbetween the action bar and the breech block by means of which the latter is reciprocated, primarily for the purpose of cooking the gun and for reloading the'same in a manner quite customary in devices of this character.

One of the main features of this invention is the cartridge carrier or lifting member now to be described.

It will be observed by reference to Figs. 14: and 15 that" the carrier 30at its forward end is provided'with a hook-shaped element 31 which is formed byslotting the body of the material from which itis made as indicated at 32. Leadingto this slot across the neck of the hook element 31 is a lateral groove 33' and adjacentto the opposite end of said slot 32 the carrier is formed with a lower projection or extension constituting a cam 34. This cam is also formed with a lateral groove Referring now to- Fig. 2 of the drawing it will be observed that the carrier 30 is pivoted at 36 between the receiver sections andin advance of the hammer 2, said carrier being provided at its rear extremity with 3 projection 37 with which the recessed edge, indicated 38, of the hammer 2 is adapted to coact upon the release of said hammer as in the firing of the gun. The carrier 30 is normally disposed in the full line lowermost position shown in Fig. 2 ofthe drawing,- in which position the head of the carrier lies at the opening of the slot 27 in the actionbar 25. In such normal position the dog 28 abuts against the edge of the forward ex tremityof the carrier, and, therefore, the action-bar is locked against sliding move ment. Before describing the operation of these parts, it will be mentioned thatthe carrier 30 is held in its normal locking posiranged locking element 40 constituting a part of the safety locking mechanism for this construction. It will be noted in F ig; 19 that the element 40 is provided with an attenuated portion 41 extending through a slot42 at the forward portion of the trigger 3 and disposed transversely of the trigger 1,181,0 4; Y a a i ss extremity is a laterallyshiftable pi 43 having jarecessed. portion-44 which coacts w ith the 'attenuated,porti'on 41 of thepiece ALOand a slot45 through which thelower extremity 40' .of' said piece 40- extendsinto o the trigger guard 3; This safety locking I arrangement is operated by shiftingthegpin 43 laterallyuntil the recess 44 lies directly 1 beneaththe forward extension'of the trigger} 1 ;I3,' as1 seen inFig. most clearly where .said tr gger may be moved on its pivot and the gun fired, To lock the gun in safety p,osi-. e.

tion the pin 43 is -n1oved laterallyintothe i dotted line position shown in'Fig'. 5 [until the recessed is out of registry with the spring for the'carrier aswill be. apparent to those skilled infthe art to'which the inven- Ation refers. The trigger 3 is normally held,

' in-position'by the spring 3 c oacting with itsforward extremity. V g 41:11 Describing the operation of this 'mech- '1 anism, and referring first to. Fig. 2- of' the drawings, when the gun is fired, andthe hammer :2 thrown said hammer impinges againstv the rear extremity ofthecartridge carrier 30 moving said carrierfinto the dotted line position whereby the action-bar is released by reason of the fact that. the

lat'eral groove 33; of the carrier'is brought 0 into a, position in-registry with the" dog 28 on said action-bar. In this position it' will also' be understood "that, the carrier is,

"brought. into contact with the --cartridge j which is held in position against the face of. the breech block-L 8 by the magazine pl-unger ul9,. just above-theforward end of the'carrier operating between the spaced I legs20' and 21 of said breech block. This 7 initial movement of thecarrier has,;there-:

Q fore, raised the rear end of this cartridge 3 moving forwardly and in the meantimethe dog 28 whichvhas reached the slot 32, .eiigageson top of the hook extremity, riding I therealongjand causingthe carrier togr'ad Iually reach its initial position. When the f carrier reaches its lowermost position the,

, until it' 'i's engaged with the grooved face of V "the breech blOCk-' The action-bar 25 being free to movearearwardly by actuating the same; throughthe ;,instrument ality of the $.55, forearm 26', the dog28 will ride over the "neck "of the cartridge, carrier, by reason of aflctsfuponthe cam surface 32 of said car rierocausingthe carrier to beralsed as the cam surface' 32 of said, carrienuntil the rtridgeis brlO lght nto pos t onwst below the groove 33' until it drops into the camsl0tx32 of the carrier. ,The dog 28 then' faction-bar:moves rearwardly' The cartridgein this second stage of hftlng'move ment of :the carrier rides upon'the upperj the grippieces 10' and ll' of the'breechblock 8. Upon the initial movement of the action;

bar 25' the cam. extension 21' of the breech" T I I block moves downwardly into the recess 29 of the action-bar, thereby dropping therec'oil projection from engagementfl with-rthe ,wau of'the recess 23 and operatively connecting the breechblock to the action bar forvmovee' Q ment rearwardly therewith; jAs thebreech blockreaches itsjrearmost;position; shown 7 in Fig. 3,'the empty cartridgeheld by the gripping elements of the breech block is ejected in the manner hereinbefore clearly] described. Furthermore','the dog 28 havingreachedin this-rearward movement of the g0 action-bar and breech block, the cam .eXten-' si0n 31: on the carrier is causedto ride thereover through the lateral groove 35'of said. I,

, extension until it engages therear cam surface of thisextension 34.] The action-bar 35;

, is now moved in the opposite direction by f the operator whereupon the dog 28 acting upon the cam extension 34 just mentioned imparts the third degree of movement to the carrier which is an'abrupt movement caus- 9 3 ing saidca'rrierto shift the cartridge, whichv has been moved up the face of the breech, block, into position between the grip .piecesf .10dand1l thereof, said grip piecesj posie v ftively holding the cartridge in position forge.

introduction into the bore -7 of the barrel: when the breech block has been moved into closed position shownin Fig; 2. Fig. 4.,

shows'the breech block in, its partial movement forwardly into the; closed position just 10' referred to with the cartridge about toenter the bore of the rifle and the carrier in its "uppermost position.

On'this return movement of the breechblock thedog 28 passes 'ofi .of'the. cam extension 34 whereupon the; i carrier 30 is suddenly moved to its normal T position with its forward extremity locking the action-bar and beneath the succeeding v cartridge passing from the :magazine intok v a position against the face of the breech block q The dropping of the carrier is causedin this mechanism, by reason of the fact that,- the upper edge of the carrier is provided with an additional'cam surface 32". which is impinged by the breech block when it isl ls spring 39 tends to hold it'dtheref In theupzine. totakethe place ".of'the one which is being. lifted into the receiving position upon,

the breech block and this forward end holds said cartridge from jamming or PI-O16Cl31QIlJ.- j

from the magazine improper time, or .1 10

until. said carrier dropsto its normal position shown in full lines in Fig. 2.

The breech mechanism of this invention is adapted tobe manually released and for this purpose the receiver frame is formed with a chamfered recess 46 therebeneath whereby the operator may press upwardly on the carrier 30 until the action-bar is released in the manner hereinbefore described. This enables the ejection of a bullet that may not be desired where different length bullets are employed or in the event other operations incidental. to cocking of the gun, etc., may be desired.
